For years, doctors and governments have been trying to wean smokers from their habit. It is a tricky task. Nicotine is just as addictive as heroin and cocaine. There are numerous officially endorsed techniques for quitting. People can try inhalators, gum, lozenges, patches, nasal sprays and prescription medications. All can help, but few replicate all the physical and social rituals that surround cigarettes. That limits how appealing they may be to committed smokers.
It had been into this mix that e-cigarettes arrived in regards to a decade ago. Unlike ordinary cigarettes, which depend on burning tobacco to provide their payload, e-cigarettes work with an electric charge to vaporise a dose of nicotine (accompanied, often, by various flavouring chemicals). They may have proved increasingly popular, especially in America, Britain and Japan. Public-health officials have been quick to conclude that they are much better than smoking. Consumers, says Robert West, a professor of health psychology at University College London, are “voting with their lungs”.
Still, not many are happy. E-cigarettes are new, so information regarding their effects remains scarce. Others be worried about who may be making use of them. The Food and Drug Administration, an American regulator, says it has data showing an “epidemic” of vaping among teenagers which it can release inside the coming months. Earlier this month it put vapor cigarette on notice that they have to attempt to combat underage use of their products and services or face sanction. How worried should vapers-or their parents-be?
The chemistry is the best starting point. Cigarette smoke is genuinely nasty stuff. It has about 70 carcinogens, as well as deadly carbon monoxide (a poison), particulates, toxic chemical toxins including cadmium and arsenic, oxidising chemicals and assorted other organic compounds.
The composition of e-cigarette vapour varies between brands. A best guess implies that, instead of the thousands of different compounds in cigarette smoke, it contains merely hundreds. Its main ingredients-propylene glycol and glycerol-are considered to be mostly harmless when inhaled. But which is not certain. People who have chronic exposure to special-effect fogs used in theatres-that contain propylene glycol-have reported respiratory problems. Nitrosamines, a carcinogenic family of chemicals, have iswmmh seen in electronic cigarette vapour, albeit at levels low enough to become deemed insignificant. Metallic particles from your device’s heating element, like nickel and cadmium, are also a problem.
The JUUL is an extremely unique and innovative e-cigarette and differs in shape to the other devices in this article, although it’s roughly exactly the same size as some of the smallest e-cigs tested! Their intuitive sophisticated Apple-like design results in a quite simple and powerful e-cigarette. Some have even been calling it the iPhone of e-cigs.
The JUUL provides the biggest throat hit of all e-cigs we tested, given its high nicotine level and vapor production. The JUUL can also be quickly recharged using its magnetic USB charging adapter. The pods hold .7 mL of e-liquid and last a surprisingly long time. You can easily understand why plenty of experienced vapers pick the Juul for stealth vape when they are out and about!
Some reports have learned that e-cigarette vapour can contain high amounts of unambiguously nasty chemicals like formaldehyde, acetaldehyde and acrolein, all based on other ingredients that have come across high temperatures. The vapour also contains free radicals, highly oxidising substances which could damage tissue or DNA, and which are thought to come mostly from flavourings. Based on work published this January flavourings like cinnamon, vanilla and butter generate probably the most.
Several studies in mice have confirmed that this vapour can induce an inflammatory response in the lungs. In June, for example, Laura Crotty Alexander on the University of California San Diego County and her colleagues published results which showed that electronic cigarette vapour has many different unpleasant effects, inducing kidney dysfunction as well as a thickening and scarring of connective tissue within their hearts called fibrosis. Her data suggest that the vapour can be disrupting the epithelial barrier that lines the lungs, triggering inflammation. They speculate that this could make it simpler for pathogens like bacteria to adopt hold. That could fit with recent work by Lisa Miyashita at Queen Mary University of London, which discovered that vaping makes cells lining the airways stickier and a lot more vunerable to bacterial colonisation.
